T 0 all whom it mag concern.

' Be it known that I, WILLIAM C. MITCHELL, a citizen of the UnitedStates, residing at Sydney, in the Province of Nova Scotia and Dominionof Canada, have invented a new and useful Apparatus for Handling Coke,&c., of which the following is a specification.

The invention relates to an apparatus for handling coke, etc.

The object of the present invention is to provide a simple, efficientand comparatively inexpensive apparatus, designed for handling coke andother loose material, and adapted to be arranged in front of a coke ovento receive the charge of coke therefrom, and capable of enablingsuch-charge to be quickly carried to and deposited in a car, or

other receptacle, thereby saving time and expense in the handling ofcoke, and enabling the furnaces to be recharged in much less timethanlieretofore. v

\Vith these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe'claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a longitudinal sectional view of a cokehandling apparatus, constructed in accordance with this invention. Fig.2 is a'transverse sectional view. Fig. 3 is adetail perspective view ofthe cross'head of the actuating mechanlsm.

Fig. 4 is a detail sectional view of a portion of the apparatus, showingthe scraper passing beneath the movable section of the track.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

. In the embodiment of the invention illustrated in the accompanyingdrawings,'the coke handling apparatus comprises in its construction awheeled frame 1, designed to be constructed of any suitable material andcomposed of' a bottom portion 2, a top portion 3 and supporting posts oruprights 4, located at opposite sides of the frame, which is open at theends. The bottom portion is preferably constructed of I-beams,

V and it is equipped with suitable bearings 5 a car 25.

mounted upon the frame at one side thereof 1 and connected by a train ofgears with the axle 7. The axle 7 preferably carries a large gear 12,which meshes with a pinion 13 of a counter-shaft 14:, having a gearwheel 15, keyed or otherwise secured to it and meshing with a pinion 16of the shaft 17 of the motor 11. The motor'may be electric, or any othertype, and the gearing for transmitting motion from the motor to the axle'7 may be varied to suit the size and weight of the apparatus and tosecure the desired speed. H z 4 The wheeled frame carries a platform 18,constructed of heavy sheet metal, such as boiler iron, or other suitablematerial and preferably arranged in the form of a chute or trough,comprising a central horizontal portion 19, and sides havin lowerinclined portions 20 and upper vert ca lgportions 21, but the shape ofthe platform'inay be varied,

as will be readily understood. The upper edges of the sides are,preferably secured to horizontal bars 22, interposed. between the sidesand the posts or uprights, 4, as clearly shown in Fig. 2 of thedrawings. The front end 23 of theplatform extends in advance of theframe and terminates above a track 24 to enable the coke to bedischarged into The track 24'is. on a lower level than the track formedby the rails 10, so that a car maybe readily run under the outer ordischarge end of the platform.

In practice the charge of coke 26 is delivered onto the platform at theinner portion thereof in an incandescent state by means of a ram (notshown), and the coke is swept or carried along the platform to the frontend thereof and discharged into the car 25 by means of a transverselydisposed conveying member 27. The cars 25 in practice are constructed ofWood and the coke is quenched after being placed i the cars; Thetransversely disposed cok -con.veying member 27 is preferably in theform of a scraper and may be constructed of'a-ny suitable material, buta rake or other analogous conveying member may be employed, if'desired.The scraper 27 is tapered downwardly to conform to the configuration ofthe platform, and it has its lower portion 28 inclined downwardly andforwardly and adapted to direct or skid the coke into the car 25 when itreaches the front or outer portion of the platform.

In practice the scraper will rest upon the platform, as indicated inFig. 1 of the drawings, during its forward or outward movement in orderto carry the entire charge of .coke to the car 25. In its backwardmovement it is elevated by the means hereinafter described to arrange itclear of the charge of coke, when the same is being delivered to theapparatus.

The scraper is moved forwardly and rearwardly by over-head actuatingmechanism, preferably composed of a rope or cable 29, having itsintermediate portion wound around a drum 30 and extendin therefrom inopposite directions to terminal guide pul- -leys 31 and 32, arranged atthe front and back of the apparatus, as clearly shown in Fig. 1 of thedrawings. The drum 30 is mounted upon a transverse shaft 33, jour naledin pedestal bearings 34 and equipped at one end with a gear wheel 35,which meshes with a pinion 36 of the shaft 37 of a motor 38. Thepedestal bearings are secured to the top portion 3 of the frame, and themotor, WlllCh is also mounted upon the top of the frame, may be electricor of any other type, and it is adapted to rotate the drum forreciprocating a cross head 39 to which the terminals of the rope orcable are secured. The cross head 39, which is disposed transversely ofthe frame, is provided at the front and rear faces with eyes 40 for theattachment of the terminals of the rope or cable, and the ends 41 of thecross head slide in longitudinal grooves 42 of guide bars 43, locatedwithin the frame and secured to the top thereof, as clearly shown inFig. 2 of the drawings. The guide bars are provided at their inneropposite faces with the said grooves 42, and they support the crosshead, which, if desired, may be equipped at its terminals with suitableantifriction devices to run in the guide-ways or grooves of the guidebars. The cross head is provided adjacent to its ends with dependingintegral ears 44 for the reception of pivots 45 of arms 46, inclineddownwardly and rearwardly and provided at their lower ends withapproximately vertical attaching plates 47, which are riveted orotherwise secured to the' front face of the scraper 27. The pivots 45are preferably integral with the upper ends of the arms 46, and they arethreaded for the reception of nuts for securing the pivots in theapertures of the ears 44, but any other suitable fastening means may beemployed for this purpose. The front scraper 27 is slightly concaveowing to the inclination of the lower portion, and it forms anelficientshovel in removing the material from the platform.

Vhen the cross head is moved forwardly by the actuating mechanism, itpulls or draws the scraper with it and carries the coke to the front endof the platform and discharges the material into the carp On itsrearward or return movement, it is elevated above the plane of thematerial by means of a track consistingof opposite rails 48,-preferablyconstructed of flanged metal and secured to the inner faces of the postsor uprights, which constitute the sides of the frame. The rails 48incline downwardly and forwardly, and the scraper is equipped at itsends with flanged wheels 49, adapted to run on the rails 48 and securedto the ends of a transverse shaft or axle 50, journaled in suitablebearings 51, secured to the scraper at the ends thereof and projectingabove the upper edges of the same. The track is provided at its frontwith movable rail sections 52, arranged at an inclination and pivotallyconnected at their rear ends to the front ends of the rails 48. The railsections 52 are tapered forwardly and extend downwardly from the frontends of the rails 48 to the upper edges of the sides of the platform,and their front ends are normally supported by the bars 22. Suitableshoulders 48 and 52*, however, may be provided at the joint-or pivotalconnection for limiting the downward swing of the pivoted rail sections.This will enable, the pivoted rail sections to be arranged clear of'thesides of the platform and will obviate the necessity of supporting theirfront terminals. When'the scraper is drawn forwardly, the wheels liftthe movable rail sections 52 and pass beneath the same, and the movablerail, sections drop back to their normal position as soon as the scraperis carried forwardly beyond them. When the scraper is moved rearwardly,the wheels 49 roll up the inclined movable sections 52 of the track andare directed by the same onto the fixed rails 48, which elevate thescraper to the dotted position shown at the left hand end of Fig. 1 ofthe drawings. The propelling mechanism is stopped with the scraper inits elevated position so as to be out of the way of the material whenthe next charge is moved onto the platform. The rear portion 54 of therails 48 curves downwardly and forwardly, and the frame is equipped withrear rail sections 55, having lower curved portions 56 extendingdownwardly and for wardly in substantial parallelism with the rear endsof therails 48, whereby when the veniently utilized as rails for theflanged.

in such movement by the rear portions 54.-

of the rails 48 and the rail sections 55.

the platform, the propelling mechanismgof the scraper is started and thematerial is immediately conveyed to the front end of the frame anddischargedintothe car 25, where "it may be conveniently quenched. Theapparatus is then transferred to .the

next gven. It will be apparent that only; a-

very short time'isrequired for handling the coke, and in a very fewminutes the oven from which the coke was removed may be recharged. Inthe forward movement of the scraper the side bars 22 may be conwheels ofthe scraper, but by allowing the scraper to rest upon the platform,lower guides may be omitted, itbeing only necessary to provide means forsupporting the scraper at the extreme front end of the platform toprevent the same from dropping, should the lower edge of the scraper becarried slightly beyond the front end of the platform.
